MESSKO® MTRAB® 2.5

About this product

Maintenance-free dehydrating breathers Ever longer operating times and ever higher current densities lead to constantly increasing demands on operating equipment. The maintenance-free MESSKO® MTRAB® 2.5 dehydrating breathers continuously dehumidify and monitor the breathing cycle of power transformers – in all climatic zones. They regenerate themselves. This ensures maximum operating times and safety, and also massively reduces costs. The MESSKO® MTRAB® 2.5 devices have been proven over 100,000 times worldwide. The intelligent algorithm ensures that the IEC 60076-22-7 standard is complied with at all times. Your Advantages at a Glance Reduces operating costs and increases operational reliability Actively protects the insulation medium against humidity Condition-dependent and self-learning algorithm Significantly higher efficiency than market competitors Easy to integrate into ETOS® – Embedded Transformer Operating System Simple to retrofit on existing equipment Successful around the world and fit for the future in accordance with IEC 60076-22-7 Choose your MTRAB® MTRAB® DB100 The MTRAB® 2.5 DB100 with alpha-control is a condition-controlled system, recommended for use on tap changers, arc suppression coils, air-filled cable terminal boxes and traction transformers. The desiccant is regenerated depending on the condition. Silica gel fill level: 1,1 kg with α-control. Good to know: The main function of dehydrating breathers is to dehumidify the ambient air. As a result of the thermal compression of the insulation medium, the ambient air flows from the environment to the expansion tank of the transformer and tap changer (referred to as inhalation). During inhalation, moisture must be prevented from penetrating into the equipment with the air flow, as this reduces the insulating effect due to the contamination of the insulating medium. MTRAB® DB100T The MTRAB® 2.5 DB100T with beta-control is a self-learning system, recommended for use on transformers with cyclic loads (network transformers, phase shifters, reactors). In addition to monitoring the humidity, the device determines a time window in which the oil conservator exhales and the desiccant is regenerated. Silica gel fill level: 1,1 kg with β-control. MTRAB® DB200T The MTRAB® 2.5 DB200T with beta-control is a self-learning system, recommended for use on transformers with cyclic loads (network transformers, step-up transformers, phase shifters, reactors). In addition to monitoring the humidity, the device determines a time window in which the oil conservator exhales and the desiccant is regenerated. Silica gel fill level: 2,2 kg with β-control. MTRAB® DB200D The MTRAB® 2.5 DB200D with beta-control is a self-learning system, recommended for use on transformers with cyclic loads (generator transformers, network coupling transformers, phase shifters, reactors, HVDC transformers). In addition to monitoring the humidity, the device determines a time window in which the oil conservator exhales and the desiccant is regenerated. Silica gel fill level: 2 x 2,2 kg with β-control. MTRAB® DB200G The MTRAB® 2.5 DB200G with gamma-control is ideal for special applications, such as cavern transformers, furnace transformers and GSU machine transformers with aperiodic breathing behaviors. If the humidity level in the air flowing towards the transformer exceeds the standardized value, the desiccant chambers are regenerated in sequence. Silica gel fill level: 2 x 2,2 kg with γ-control. Software The MESSKO® MTRAB® 2.5 is equipped with a data logger of the latest generation as standard (software optional). The MTRAB® MSET software allows to monitor and analyze the device function and processes (dehumidification and regeneration) at any time. This provides additional safety when monitoring the equipment. In addition, you benefit from the long-term analysis – recording of the important operating parameter residual air humidity over a period of up to 10 years. Available languages: English, Chinese, French, German, Italian, Korean, Portuguese, Russian and Spanish The dehydrating breather for transformers and tap-changers from the market leader Effectively prevent moisture in the insulation medium LOWERING OPERATING EXPENSES, EXTENDING SERVICE LIFE 100,000 times tested and proven worldwide – even under the most extreme conditions. MESSKO® MTRAB® 2.5 is a tried and tested system – fit for the future in accordance with IEC 60076-22-7. Technology from the market leader: dehumidifies and continuously monitors the respiratory cycle of the power transformer. Considerable cost savings. The latest technology for optimum operation and reduced operating Ccosts Data logger incl. software (software optional) Extended overvoltage protection in accordance with EN 60664-1 Category III IP66/IP67 degree of protection Corrosion protection C4H, C5H or CX in accordance with IEC 12944 Test button for manually checking the function, moisture level at the device output and message chains (included as standard) Direct integration into monitoring and SCADA systems Prepared for integration into ETOS® (optional) Maximizing operating times and reliability. Increasing efficiency. Ever-longer operating times and ever-greater current densities lead to continuously increasing demands on equipment. Optimal dehydration is the essential prerequisite for the health of your equipment. The proven solution: the maintenance-free MESSKO® MTRAB® 2.5 How MTRAB® 2.5 works In normal operation, the air flowing to the oil conservator is routed across the desiccant (silica gel) and thus dried. The degree of moisture of the air flowing to the expansion tank is permanently monitored. The regeneration of the desiccant is activated when the moisture content reaches the defined limit value depending on the behavior of the equipment. The intelligent algorithm and design ensure compliance with the IEC 60076-22-7 standard and the required limit values. Summary: The maintenance-free MESSKO® MTRAB® 2.5 prevents the ingress of moisture into the insulating fluid of transformers, tap-changers, and other components and permanently monitors this equipment.
